Now that the Samsung Galaxy S9 has been unveiled, and almost ready to reach the hands of phone-users everywhere, the rumours have had to switch gears. So we've started hearing all about the Galaxy Note 9, which will probably arrive in five or six months. The latest bit of news claims that the phone won't have that coveted in-display fingerprint scanner.

Bear in mind that this information comes from KGI Securities analyst Ming-Chi Kuo, rather than any more solid hardware leaks from the production line, but he does have a decent track record with this sort of thing. He claims that Samsung won't have the in-display fingerprint sensing technology ready for the Note 9 due t "technical difficulties" - mimicking a similar report about the Galaxy S9 that the company released last August.

That report said that the company had been experimenting with the hidden sensors, though they wouldn't appear on the S9. As we've already seen the S9's fingerprint scanner is on the back, located just beneath the camera.

In-display fingerprint scanners are quite new. It's only just started appearing in phones at CES and MWC, and most of those are concepts that you can't actually buy yet. While various promising pieces of tech have existed for a while, the fact that it's still so new means it's going to be a while before we start seeing more widespread adoption. That may be especially true of big companies who might want to opt for their own proprietary system, rather than licence a patent from someone else.

So don't expect to ditch the physical fingerprint scanner anytime soon. Not unless you can find a phone you like with decent facial recognition, or are willing to forgo biometrics altogether. [TechRadar]
